New MSM7850 Chipset Delivers 9.3 Mbps Data in Field Trials
SAN DIEGO, March 26 /PRNewswire-FirstCall/ -- QUALCOMM Incorporated (Nasdaq: QCOM - News), a leading developer and innovator of Code Division Multiple Access (CDMA) and other advanced wireless technologies, today unveiled the addition of a new product supporting CDMA2000® 1xEV-DO Revision B to its roadmap. The new Mobile Station Modem(TM) (MSM(TM)) MSM7850(TM) chipset is the industry's first device solution for EVDO Rev. B, delivering highly advanced capabilities for next-generation data and multimedia services. QUALCOMM's recent field tests of EV-DO Rev. B technology resulted in average data rates of 9.3 Mbps on the downlink over 5 MHz of spectrum.
"The evolution of CDMA2000 networks from EVDO Rev. A to EV-DO Rev. B allows network operators to remain leading-edge in their service and performance offerings without the need for any infrastructure hardware changes," said Dr. Sanjay K. Jha, chief operating officer of QUALCOMM and president of QUALCOMM CDMA Technologies. "QUALCOMM's technology will allow 3G CDMA networks to meet next-generation data requirements."
The MSM7850 device chipset provides support for EVDO Rev. B with full backward compatibility. Scheduled to sample this year, the MSM7850 solution provides manufacturers with a highly integrated, flexible solution to deliver the capabilities of Rev. B on consumer products. A software upgrade release to enable QUALCOMM's Cell Site Modem(TM) (CSM(TM)) CSM6800(TM) solution to support multi-carrier EVDO Rev. B will be available by the end of March 2007.
EVDO Rev. B. enables applications such as mobile TV or streaming music with a concurrent voice call, or conducting a Voice over Internet Protocol (VoIP) conversation while simultaneously browsing the Internet or transmitting multimedia content over the network. The flexibility of EV-DO Rev. B technology also enables significant network capacity and performance enhancements while leveraging existing network investments and currently deployed devices. High-performance devices could support forward-link data rates of up to 73.5 Mbps, while lower-cost or pre-existing devices could support 4.9 Mbps. Network operators may reduce their costs by allowing a greater percentage of spectrum to be allocated to IP-based services. |
Based on history of Qualcomm announcing, the carriers adopting and then consumers seeing a new technology, it could be another 2 years before this is on the markey.
BUT, it is exciting, knowing that EVDO is going to get a lot faster

Here is what we learned about EVDO Rev B from Qualcomm today at CTIA 2007:
- Software only upgrade for EVDO Rev A Towers
- Requires new chipset for PC Cards (EVDO Rev A cannot be upgraded - you need a new card)
- Available to carriers later this year, could be later 2008/2009 before available?
- Current EVDO Rev A has a maximum of 3.1Mbps, Rev B uses 3 channels to achieve the 3X speeds (or 9.3Mbps).
- Verizon or Sprint have not yet announced they are going to Rev B (yet).
- in a demo we saw, streaming of 8.7Mbps - 9.0Mbps was constant.

Any improvement in latency over Rev A?
